如何优雅地关闭盗用码头

Question

我有一个应用程序运行在嵌入式jetty服务器上。现在我想将服务器作为服务启动/停止。我使用一个脚本来启动服务器。

java $JAVA_OPTS -DREQ_JAVA_VERSION=$JAVA_VERSION -jar myjetty.jar

Server server = new Server();
SelectChannelConnector connector = new SelectChannelConnector();
connector.setPort(PORT);
server.addConnector(connector);
HandlerCollection handlers = new HandlerCollection();
NCSARequestLog requestLog = new NCSARequestLog();
requestLog.setFilename(home + "/logs/access_" + logFileDateFormat
            + ".log");
requestLog.setFilenameDateFormat(logFileDateFormat);
requestLog.setRetainDays(10);
requestLog.setAppend(true);
requestLog.setExtended(false);
requestLog.setLogCookies(false);
requestLog.setLogTimeZone(TimeZone.getDefault().getID());
RequestLogHandler requestLogHandler = new RequestLogHandler();
requestLogHandler.setRequestLog(requestLog);
handlers.addHandler(requestLogHandler);
server.setHandler(handlers);
server.start();
server.join();

从Jetty 7.5.x开始，您可以在代码中使用org.eclipse.Jetty.server.handler.ShutdownHandler:

java prettyprint-override">Server server = new Server(8080);
HandlerList handlers = new HandlerList();
handlers.setHandlers(new Handler[]
{ someOtherHandler, new ShutdownHandler("secret_password", false, true) });
server.setHandler(handlers);
server.start();

...这将允许您通过发出以下http POST请求来关闭码头：

curl -X POST http://localhost:8080/shutdown?token=secret_password
